WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent N 0. 671,727, dated April 9, 1901.

Application filed October 20, 1897. Serial No. 655,838. (No model.)

To all whonz it may concern.-

Be it known that we, ESPIRIDION HIPOLITO and ASA MASTIN, citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvementsin Window- Screens, of which the following is a specification.

Our invention relates to means for securing the sheet of wire-gauze or other material in the sash or screen frame.

One object of our invention with relation to fastening the gauze or other sheet to the sash is to provide convenient, cheap, and very effective means for perfectly securing the sheet in place and drawing it taut and preventing it from becoming loose. We avoid nailing through the sheet and clamp the edges of the sheet by bending the same over a sharp corner, a strip having a sharp corner being inserted into a groove having a sharp corner into which the edge of the sheet is bent, and the strip is fastened to the main member of the sash.

Another object of our invention is economy in putting the frame together; also, to provide very simple and inexpensive means for giving a bevel finish to the gauze-fastening strip. For fastening strips we use strips which are cut from the main membersthat is, the stiles and rails of the sashand make the strip of such form as to give the greatest strength with the smallestcross-sectional size.

The accompanying drawings illustrate our invention.

Figure l is a view of our improved screen with portions of one of the stiles broken away to show interior construction. Fig. 2 is an enlarged fragmental detail of the same also broken away. Fig. '3 is a cross-section on line 3 3, Figs. 1 and 2. Fig. 4 is a sectional View which shows a screen in process of construction. The mechanism for applying the wire-gauze is also shown. Fig. 5 is an end view of a stile with strip just cut from it. Dotted lines indicate the groove to be cut and also the portions of the strip which will be removed by a planer to give the strip the preferred rhomboidal shape.

Our invention comprises the combination of the main member, such as the stile A A or rail B B, having in one face, near the edge thereof, a groove the faces or walls of which are indicated by numerals 1 2 3, a sheet 0, with edge thereof bent into the groove and resting on the bottom and one wall of the groove, and a strip D, fitted in the groove above the sheet and fastened to the main m ember by nails 4c or any other suitable means. The outer wall 2 of the groove is preferably higher than the inner wall 3, the difference in height being practically equal to the smallest diameter of the fastening-strip D, and in the process of manufacture the fastening-strip is cut out of the main member, as indicated in Fig. 5. After the strip has been cut out, thus leaving the low wall 3, the groove is then out between such-wall 3 and the Wall 2 and the strip is made rhomboidal diamond-shaped, its angles and dimensions being such that it fits above the sheet in the groove and comes flush with the taller outer wall and projects above the lower inner wall and slopes from the edge which is at the outer wall in ward to its inner edge, thus making a neat finish. The bottom face or wall 1 of the groove is oblique to the side walls thereof, and the strip has in the groove three faces, two of said faces-viz., those opposite the walls 1 and 2being at an obtuse .angle, and two-viz., those opposite the walls 1 and 3being at an acute angle with each other and fitted in the groove above the sheet and fastened to the main member by nails 4;, which are driven through the strip into the stile or rail without passing through the sheet. The gauze sheet can at any time be removed by first drawing the nails and then taking out the strips.

To apply the gauze sheet 0 to the sash, a beveled wheel E, carried by a shaft e, which is mounted in a support e on a frame E and is pressed downward by a spring 6 and is operated against the pressure of the spring by a lever 6, may be used in the following manner: The stiles and-rails being fastened together, the gauze sheet will be placed on the sash,-resting upon the inner walls 3, and the sash will be laid on the frame E and the wheel E brought onto the wire-gauze at one of the corners formed by the stile and rail of the sash. The wheel under the pressure of the spring bonds the gauze down into the groove. Then the sash will be pushed along beneath the wheel, the pressure of the spring 6" being sufficient to bend the gauze sheet down into the groove as the wheel engages the gauze. After this a strip will be placed in the groove over the gauze and will be fastened by the nails; The process described will then be gone through with the opposite side and with the ends of the gauze sheet, thereby securing the sheet in place all around its edges. When thus secured, the sheet will be perfectly tight and will be secured against drawing out of the grooves.

One of the stiles A A is grooved at one edge with a groove a,'and spring-sockets 5 5 are made in the grooved edge. Spiral springs 6 are seated in the sockets. A tongue F is seated in the groove and provided with transverse slots f, corresponding in position with the eprings in the stile. Staples 7 are set in the tongue F and extend across the said slots, respectively, and rest on the said springs, respectively, and the pins G are inserted through the stile and through the slot to intercept the staples and prevent the withdrawal of the tongue F. By this construction the staples 7 form seats for'the springs 6, and the pressure of the springs does not tend to draw the tongue F away from the staples when the staples engage the pins G.

Now, having described our invention, what we claim as new, and desire to secure by Letters Patent, isr 1. The combination of the main member having in one face near the edge thereof a groove the inner wall of which is lower than the outer wall and the bottom of which groove slopes from the outer wall to the inner wall to form an obtuse angle with the outer wall and an acute angle with the inner wall; a sheet bent in such groove; and a strip having in the groove three faces, two faces being at an obtuse angle and two faces at an acute angle with each other, and fitted in the groove above the sheet with the acute angle in the sharp corner formed by the inner wall and bottom of the groove.

2. The combination of the main member having in one face near the edge thereof a groove the inner wall of which is lower than the outer wall and the bottom of the groove sloping from the outer wall to the inner wall; a sheet resting on the bottom of the groove and upon the inner wall; and a strip, diamond-shaped in cross-section fitted in the groove above the sheet and there fastened and having one edge flush with the outer face of the outer wall.
